Oxalic Acid Anhydrous Producers 98%min is a fine chemical product. It is mainly used in the ester, chemical synthesis, daily chemical and pharmaceutical manufacturing in the water -free state. The production cost is very high. It does not mean that kind of oxalic acid without surface water. It is a product without crystalline water. Molecular formula (H2C2O4); CAS: [144-62-7]. The second water oxalic acid does not contain surface water. Some people mistakenly think that it is no aquatic oxalic acid, but contains two crystal water (COOH) 2.2H2O.

Background and Overview
Oxalic Acid Anhydrous Producers 98%min is produced by Oxalic Acid Anhydrous Producers X-Humate Group, and is also known as "Oxalic acid". It is a colorless transparent crystal, which often exists in plants such as rhubarb in the form of calcium salt. It has strong acidity and is not flawed. Oxalic acid Anhydrous can be used for organic synthesis.
Preparation:
(1) After all production reaction containers are replaced with nitrogen, they are placed under the protection of high -purity nitrogen to add materials;
(2) Add the dry quantitative water -free tetrafluorosyls and catalysts to the quantitative organic solvent of the stirring reactor to dissolve and formulate it into a solution;
(3) Slowly add quantitative water -free oxalic acid or hydraulic acid solution to the lithium ostefluorofluorozomyrametetic acid solution, and fully reacts under the control of the specified temperature, prescribed pressure, and tail gas absorption solution to obtain lithium diexyraxide solution. The catalytic synthesis method of lithium boric acid boric acid in the present invention has a simple process route and a high product revenue. The exhaust gas generated during the reaction process is absorbed by alkaline solution without environmental pollution.
